      §2. To slide, roll, tumble, walk, creep, run, dance, leap, skip, and
abundance others, that might be named, are Words, which are no
sooner heard, but every one, who understands English, has presently
in his Mind distinct Ideas, which are all but the different modifica-
tions of Motion. Modes of Motion answer those of Extension: Swift
and Slow are two different Ideas of Motion, the measures whereof
are made of the distances of Time and Space put together, so they
are complex Ideas comprehending Time and Space with Motion.
